This invention relates to mechanism for inserting fastenings andparticularly to means for supplying fastenings in an lnserting machine.

The invention has for its object to provide improved means forcontrolling the delivery of fastenings whereby waste of fas- 5 teningsby delivery to the inserting mechanism when no work is in position toreceive them will be avoided.

The invention is herein shown, for the purpose of explanation, asembodied in the tacking mechanism of a lasting machme of the type shownin United States Letters Patent N o. 58&,74;4c, but nothing herein is tobe understood as limiting the invention to use in any particular machineexcept as definitely stated in the claims.

A very important feature of this inven tion consists in the provision ina tack delivery controlling mechanism of means for delivering a tack inposition to be driven during the first actuation of the driver after thecontrolling mechanism has been set to start the delivery of tacks. Inthis respect this invention possesses a marked advantage over the priorart as represented by the United States Letters Patent No. 663,471. Inthat construction a complete cycle of operation of the machine isrequired before a tack is presented for insertion. In the preferredconstructions embodying the present supplying mechanism is stopped witha tack in position to be delivered to the driver in its first descentafter the supply mechanism is restarted. This feature of this inventionhas the advantage that no delay occurs in the use of the machine beforea tack can be driven, and the further important advantage, when embodiedin a lasting machine, that a tack is supplied in position to be drivenfor holding the portion of upper that is overworked 1n the first cycleof the operation of the ma chine.

It is a further characteristic of the preferred embodiments of theinvention that the tack supplying mechanism is not dependent upon thedriver for its actuation and can be stopped without necessarily stoppingthe driver.

An important feature of the invention consists in providing acontrollable connect-ion between a continuously moving actuator and thetack delivering devices and means whereby said connection is adjustedautomatically when the work, as for example, a shoe, is presented andremoved. In the machine shown a cam plate serves as the actuator andreceives a continuous reciprocatory movement while the machine is inoperation. Cooperating with this cam plate is a lever that actuates thetack separator and causes a tack to be separated from a row of tacks inthe raceway and delivered to the tack block at each operation of themachine. I have located a movable shifting device in position to beengaged by the shoe when the latter is presented to receive a, tack fromthe tack block and have connected this shifter with the tack supplyingmechanism so that the latter is controlled by the position of theshifter. In accordance with a further feature of this invention theparts of the tack supplying mechanism are arranged to maintainconnection at all times while being ad justed by the shifter to startand to discontinue the delivery of tacks. In an illustrated embodimentof this feature of the in vention the cam plate has a movable connectionwith its carrier and the shifter is connected with means by which thecam plate is locked in a fixed relation to its carrier. Obviously manyother arrangements might be devised which would be the mechanicalequivalents of that shown.

In accordance with another feature of this invention the lever thatactuates the tack separator is held in operative relation to the camplate by a movable controlling member which is connected to the shifterand adapted, when no shoe is in the machine, to permit the lever toremain at rest at the outer limit of the throw effected by the camplate.

A novel characteristic of this invention which is of great importance isthat when rating and delivering devices which sepa; rate a tack duringtheir stroke m-one direction and deliver the tack during their returnmovement. Provision is therefore made that the mechanism shall come tore'st' with a tack separated and ready to be delivered on the firststroke after the mechanism is again set into operation.

A further improvement in the tack supplying mechanism comprised in thisinvention consists in a novel construction of the feeding mechanismwhereby access can be readily gained to the tack separating devices forremoving tacks that sometimes get caught or jammed in said devices, orfor replacing worn parts of said devices. To

this end the end block or delivery table over which the separated tackis moved to be delivered is formed so that it can be readily detachedfrom the other portions of the feeding mechanism and will expose theseparating devices to the view and manipulation of the operator. l V

These and other features of' the inven tion, including certain detailsof construction and combinations of parts, will be more fully explainedin connection with the following description, and will then be pointedout in the claims.

Figure 1 is a side elevation of a portion of the lasting machine, beforereferred to, with the present improvements applied thereto; Fig. 2 is asectional plan View on the line 00a2 of Fig. 1; Figs. 2 and 2 are viewsshowing different positions of the parts illustrated in Fig. 2; Fig. 3is a side view showing another construction; Figs. 4 and 5 are planviews showing in different positions parts that appear in Fig. 3; Fig. 6is a perspective view of the end portion showing the raceway and thetack feeding mechanism, and illustrating also means forremovablyattaching the end block or delivery table of the raceway; Fig. 7 is asectional view showing the latch for the delivery table.

' ersing the end of the raceway, passes between the lowermost tack inthe raceway groove that occupies the operative position and the tacknext above the lower one. A delivering plate 6 having a pointed finger 8and a slot 10 inclined to the path of its movement forces the separatedtack toward the discharge opening 12 in the table orend block 14 Fig. 7.The separating and delivering devices4 and 6' are connected for endwisemovement to a rack bar 15 that is engaged by teeth on the frontend of alever 20. This lever is shown as formed in two parts which are connectedto yield against the'pressure of the spring arranged inn socket in onepart of said lever and pressingagainst a plunger 2-2 which engages theother part of the lever. Thelever has a roll 24 on its rear end thatengages the inclined face of a cam plate 25. This plate is permanentlymounted upon its carrying slide 26 which is connected to the main shaftof the machine for continuous endwise reciprocation as shown in saidLetters Patent N 0. 584,744. The slide 26 also carries the tackblock 28which has the driver passage 30 provided with any usual tack sup-.

porting fingers. The tack block moves from aretracted position where itreceives a tack from the discharge opening in the end block 14 to anadvanced position over the work and under the driver 32. In thismovement the cam plate advances, throwing the rear end of the lever 20outwardly and carrying the front end to the left and the tack separatingand feeding devices into the position in which they are shown in Fig. 2.In this position the lowermost tack in the operative raceway groove canslide down into the inclined slot 10. In the normal operation thereverse or backward movement of the tack block will be accompanied by areverse movement of lever 20 forced to the discharge opening 12 throughwhich it will fall into the driver passage of the tack block at the timethe latter reaches its receiving position.

In the construction shown in Figs. 1 and 2 the movement of the leverfrom the position shown in Fig. 2 for delivering a tack is efiected by amovable cam plate 40. 'This' plate is pivoted to a plate 25 fixed to theslide 26 and has a face 42 which preferably is at all times in contactwith the roll 24 and which, with the plate 25, forms an inclined trackfor the roll. This inclined cam path, when the parts are in the positionshown in dotted lines in Fig. 2, compels the rollto move inwardly as theplate moves ba.ck-

gages the inclined spoon-shaped face 54 of the bar 40, rocking that barinto the dotted line position and positioning the rollv24 and.

the separating devices connected with it in their proper relation to theplate according to the point in the cycle of the machines operation atwhich the presentation of the shoe takes place. This provides that atack will then be delivered in regular time relation to the movements ofthe driver and other operating parts of the machine. Fig. 2 shows infull lines the position shown in dotted lines in Fig. 2 and Fig. 2 showsthe position of the parts when the tack block has advanced with the tackto a position under the driver. As the shoe is presented the plunger 45is forced inwardly against the cam plate 40, forcing it into operativeposition relatively to its driver and, finally, slides on to thespoon-shaped end 54:, Fig. 2*, of the cam plate whereby the cam plate islocked in position relatively to the plate 25 and its driver and remainsin that position as long as the plunger remains in, or the shoe remains.in, position. It will be seen that the bar 45 is in locking engage mentwith the end 54 of the cam 40 some time before the shoe is fully inposition to be operated upon. The end 54;, as the machine operates,slides back and forth along the plunger 45 and when the plunger isforced in to the fullest extent by the presentation of the shoe,considerable movement of the plunger must take place before the camplate 40 becomes unlocked and the separating devices are renderedinoperative, just as is the case with the lock 66 of Figs. 3, a and 5 ofthe drawing. If the cam plate 25 is in its retracted position shown inFig. 2 actuation of the cam plate 40 by the op erating member 50 willmove the lever 20 and cause the delivering device to move toward theright and drop a tack at once into the tack block. If the operatingmember 50 is actuated when the parts are in any other position than thatshown in Fig. 2, then it will cause a tack to be delivered in the samecycle of the machines operation and as soon as the tack block does reachits tack receiving position. By this provision for stopping thesupplying devices with a tack in the delivering device the operator doesnot have to wait until the machine makes a complete cycle for separatingand then delivering a tack, as it would have to do if it were stopped atthe other end of its throw or if the lowermost tack were stopped in theraceway above the separating devices. This is of particular importancewhen the grippers 55 are employed and the tack is depended upon forsecuring the portion of upper pulled by the grippers. An adjustable stop56 is shown for positioning the separating devices accurately withrelation to the raceway groove.

1n the construction shown in Figs. 3, 4 and 5, which also possesses theadvantage that the mutually contacting parts of the driving and drivenmembers of the separator The cam plate has also a slot at 65 that isadapted to receive the controlling device 66 which is a bar movablevertically between the slide 26 and a cap plate 68 mounted on the slide26. The bar has a shoulder 69 that rests upon a lifter 7 0 which issupported by the parallel links 7 2 and 74, on the latter of which isformed the operating member 75. A spring 76 holds the operating memberand. its connected parts in the position shown in full lines in Figs. 3and 5. \Vhen the said member is rocked about its fulcrum 78 against thetension of spring 76 the lifter is lowered, allowing the controllingdevice 66 to drop upon the cam plate, and the spring 80 forces saiddevice into the slot 65 the neXt time the slot comes under the device.When the controlling device is lifted the cam plate continues itsreciprocatory movements with the slide 26 to which it is alwaysconnected, but it has in addition a swinging movement about its pivotalconnection at 62 and the spring 82 is permitted to hold the lever 20always in the position shown in Flg. 5 and determined by the stop 56with a tack ready to be delivered as soon as the controlling device isadjusted.

The operating members 50 and 75 are each shown as arranged relatively tothe shoe bottom rest 85 of the lasting machine in position to be engagedand moved by the shoe while it is being presented in position to receivethe tack. By this arrangement the controlling device is operated withoutspecial attention from the operator to cause the feed of tacks to becommenced when the shoe is put into position to receive the tacks.

12 The end block or delivery table 14 is preferably attached to theraceway for convenient removal and for this purpose the supporting plate90, whichis permanently attached to the raceway by the screws 91, has anopen ended slot 92 to receive a guiding stud shown as a screw dependingfrom the lower face of the delivery table. The raceway, or the racewaysupporting bracket, has a positioning stud 93 project-ing from'its endface which fits into a socket in the face of the table 14. The racewaybracket also carries a latch 94, the shank of which is acted upon by aspring that presses the latch rearwardly and holds its front hookshapedend in a seat 96 in the front face of the table. A guiding thimble 97embraces the rear end of the shank of the latch and the spring while asecond thimble 98 is similarly fitted over the front end of the springand has an outstanding handle 99 which projects through a bayonet jointslot 100 in the supporting bracket. This arrangement provides that thehandle can be moved rearwardly in the locking port-ion of the slot 100,compressing the spring by sliding the thimble 98 rearwardly and then thehandle and thimble can be turned until the handle is in the long arm ofthe slot, after which it can be moved forwardly, relieving the tensionon the latch which can be unseated and turned to release the deliverytable which may be removed by a forward movement which will free it fromthe stud 93 and the slot 92. Reverse manipulation of the parts willrestore the delivery table securely in operative position. The occasionfor removing the delivery table to obtain access to the feeding devlcesarises fretquent-ly because of the presence of misformed tacks orforeign matter which clogs the delivery mechanism, and it is thereforeof great advantage for the operator to be able to remove the deliverytable quickly without the use of machinists tools.

Having explained the nature of this in vention and described a preferredconstruction embodying the same, I claim as new and desire to secure byLetters Patent of the United States driven while the machine continuesin operation, mechanism for controlling the feed- 1ng of fasteningsconstructed and arranged to cause the feeding mechanism to be startedand stopped independently of the driver and to deliver a fastening intoposit-ion to be inserted in time relation with the first descent of thedriver after the controlling mechanism has been set.
